LP Eccentric's needed adjustment as too far in to the crank and fouled the water pump eccentric.

Loosened off the grub screws to move the eccentrics over and found no evidence of thread lock. Make sure there is some on these as the grubs could come loose and either allow the eccentric to wander sideways or the screw work its way out to gouge the inner surface of the eccentric strap making a right mess of it.

As commented when I started taking the engine apart. I found the reach rods were all bowed. Well found the reason. 3 out of 4 rods have the flanges incorrectly installed.

Need a lot of heat to break the countersunk screws out of the flange fitting due to the plating.

LP side test fitted

HP side test fitted

Piston rods test fitted

Looks correct but will need to hand wind the crank and observe to make sure.

Oh while I remember.

When fitting the little end bearings and securing pins. Put the pins in from the middle. i.e. with the nuts on the outside. Otherwise you need to take the valve rods off to get the little ends apart.

My valve rods were less than straight, just put them in the vice & bent them straight. I think the brazing might have bent them, they bent back straight easily though. When fixing the eccentrics I prefer to fit two short grub screws so that the second one locks the first. I've had a bad experience with locktite & grubs screws where you can't get the little b***ers out as the heads are rounded off inside.

Hey Lynn, don't forget to turn that mud hole bracket on the boiler top through 90deg! If it were a real one doing the job it should do, it'd be making a right mess of the copper cleading ring as well as not sealing!!

Job coming along very nicely, lots of good general info for everyone!!

STW have supply of diff pinions now that fit properly & don't need to be spaced out so the teeth only just touch. Ring Steve for a set by return, there is a small charge for them though just to cover costs. Then you can have a silky smooth diff that doesn't do a hop, skip & a jump when going round corners!

Best you phone then and ask as it is your choice. Then just let me know.

On my diff. I reduced the bush size on the outside of the pinion. This allowed more radial slop and fairly cured the problem. Been running Crsytal for almost 700 hours and last year 180 road miles. Sometimes getting very stuck in mud with a wheel spinning and the diff was silent.

The diff only rotates very slowly when cornering. So unless you are doing donuts or very asymmetric traction it never moves fast enough to hear.
